Does someone have a correct drawing where the mounting holes are?
Please don't send me to the Boardsize.pdf as this is not complete (only the two internal holes are correctly referenced in X and Y. The four external has only reference in the Y axis but there is two missing in the X axis [that is going from the side where the port are located to the first hole).
I knew that you were wrong about this, but I didn't have a Due in stock to verify it.
So, I bought another one.
It arrived today.
I was right. The Mega and the Due have the exact same drill pattern for all 6 mounting holes.
